Metal roof joint



Aug. M6, 1938.. E. s. COPELAND METAL ROOF JOINT Filed Oct. '7, 1936 Patented Aug. 16, 1938 UNITED STATES PATENT OFFIQE 1 Claim.

This invention relates to metallic roofs of sectional formation, and has for the primary object the provision of means for joining the sections of the roof together to provide weather or leak proof joints therebetween and which are easy and quick to assemble and will provide drains to said joint and permits the sections to be readily stacked one upon the other for easy handling and shipping.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary perspective view illustrating a metallic roof constructed in accordance with my invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4.- is a fragmentary edge view showing one end of one of the sections.

Figure 5 is a view similar to Figure 4, showing the opposite end of the section.

Referring in detail to the drawing, the numeral I indicates generally a metallic roof made up of a plurality of overlapping sections 2 each of metallic sheet formation and constructed in accordance with the present invention. Each section 2 has formed along one edge an upstanding flange 3 and spaced ribs G and 5 adjacent thereto. The section 2 adjacent an opposite edge is provided with spaced ribs 6 and a straight edge I. The section 2 between said ribs is provided with a reinforcing rib 8. The ribs heretofore referred to are formed in the section by pressing the material of said section and which provides in an opposite face of the section grooves.

The sections 2 are assembled upon a roof construction, as shown in Figure 1, that is, said sections are arranged in overlapped relation so that one of the ribs 6 receives therein the rib l of the adjacent section. The other rib 6 receives therein the upstanding flange 3 cooperating therewith in forming a drain trough 9. The

straight edge 1 abuts one of the walls of the rib 5 and the abutting wall of the latter is disposed substantially straight while its companion wall is disposed at an inclination, as shown at Ill. The ribs 4 and 8 are provided with indentations H for the purpose of receiving the pointed 5 ends of nails or like fasteners employed for securing the sections to the roof construction. After the assembly of the sections, the ribs 5 at spaced intervals are clinched or bent downwardly, as shown at L2, to overlie the straight 10 other with the ribs interfitting so as to facilitate 20 handling and shipment.

Having described the invention, I claim:

A metallic roof construction comprising a plurality of metallic sheet sections adapted to be laid in overlapping relation and each section being bent to provide at an underlying edge an upstanding flange and a pair of spaced ribs adjacent thereto, and a second pair of ribs located adjacent the opposite edge of said section, one of the ribs of said first mentioned pair of ribs of the underlying edge having a substantially straight upstanding wall and a wall disposed on an inclination thereto, the other rib of the firstmentioned pair of ribs of the underlying edge fitting into one of the ribs of the second-named 35 rib of the first-named pair of ribs of the under- 40 lying edge being clinched at spaced intervals against the overlapping edge with the. nonflanged overlapping edge bearing tightly against the straight wall of the last-named rib thereby cooperating with the clinched portions in pre- 45 venting the sections from moving out of overlapping relation.
